The FSi carbon 1 features a Hi-Modulus carbon frame, Shimano XT brakes and Shimano XTR/XT Di2 electronic shifting components as upgrades over the FSi carbon 2. Hi Modulus carbon frames use a higher grade of carbon fibre than standard carbon frames allowing for a lighter frame whilst maintaining stiffness and strength.

Cannondale's FSi is a hardtail like no other. Taking advantage of exclusive technologies such as Ai (Asymetric Integration), Si (System Integration) and Lefty, FSi is ready to cope with the extreme nature of modern World Cup courses. With design input and World Cup podium results from XC legends Manuel Fumic and Marco Fontana, FSi has been proven to the highest level. If you're looking for a super fast and light XC hardtail with the poise for technical courses then FSi is a must.

Ai allows for super short rear stays putting more weight over the rear wheel for climb winning traction without sacrificing mud clearance or limiting you to single ring setups. Ai also allows for an evenly dished rear wheel giving better strength and stiffness

OutFront steering geometry is slack and stable for the most challenging descents yet nimble and quick in tighter sections.

All FSis feature Cannondale's Lefty fork,. Lefty offers unparalelled steering stiffness and precision for an XC fork and is super lightweight too. Don't be mislead by the single leg design, Lefty is super stiff and offers amazing tracking. Lefty's fitted to FSi models feature a custom offset to work with the OutFront geometry.

FSi wheel size is Fit Focused meaning that 29" wheel are used on Medium,Large and XLarge sizes, whilst 27.5" wheels are used on the small size. This offers the best balance of fast rolling, larger, wheels and rider fit.

FSi, an XC weapon.
